About

A quiet island. A forgotten post office. And a mountain of undelivered mail.
You arrive just in time… or perhaps a little too late. The former postman has vanished, leaving chaos behind: parcels piled to the ceiling, customers growing impatient, and a once-thriving postal service on the brink of collapse.
One package at a time, you’ll bring it back to life.

Cat Mail Co. is about slowing down and enjoying the rhythm of small, satisfying tasks.
Incoming mail arrives by boat, and outgoing parcels must be carefully loaded for their journey.
Sort deliveries for the right destinations, or risk having them returned damaged. Take your time serving customers, organize your storage exactly the way you like, prepare for the next wave, and keep everything running smoothly as the post office slowly regains its former glory.
With each improvement, new destinations unlock, along with tools and abilities to help you manage the growing operation.

Every package tells you how it wants to be handled… but how you do it is up to you.
Weigh parcels to determine postage, apply destination labels, mark fragile or heavy goods, and decorate them with a variety of stamps. Functional or whimsical, every sticker you place adds personality to your work.
There’s no such thing as a “correct” way but just your way.

The post office doesn’t sleep… and neither do you.
As night settles in, moonlight reveals secrets. What seemed ordinary during the day may carry strange properties after dark, offering magical insight into how some parcels should be treated.
The routine continues, but in a magical way.

The massive backlog left behind isn’t just a task, it’s the story of the post office waiting to be uncovered.

Run the post office solo, or with friends.
With up to 4-player co-op, you can divide tasks, optimize your workflow, or simply enjoy the routine together. Whether you’re stamping, sorting, or loading the boat, teamwork makes the mail flow.
A cozy, stress-free gameplay loop with no timers or penalties
A satisfying package handling system: weigh, stamp, label, and sort
A meaningful day/night cycle with magical nighttime mechanics
A relaxing “pre-crastination” experience focused on preparation and flow
A post office in a cat's world to organize and restore
Up to 4-player cooperative gameplay
A narrative discovered through sorting parcels

(finished) Pretty good if a bit easy, was hoping for a bit more in the way of secrets to unlock during gameplay but that never really came up. Just a sorting simulator and once you have a system down it just kind of goes through and I was never in danger of running out of storage (I don't think I ever used more than 25% of possible storage space).
Such a cute game!! It kept me engaged for a lot longer than expected (took me 15 hours to complete it in singleplayer). It's a chill and repetitive sorting game while still having enough variety, especially with all the rooms unlocked, that you have to pay attention to where you're placing things. Even if you mess up, the penalties aren't severe enough to be frustrating. I also love the fact that it's first person, but you can still see part of your model. The tail physics are so cute XD Super nice game to relax with!
Very cute game
I enjoy this game because it's chill and no pressure, however I wish there was a manual save option, or that the auto-save were more often. I've already lost about 20 minutes of progress because I've needed to go do something mid-shift, and the game only saves at the end of shift.
So relaxing fun and rewarding and genuinely so cute. <3
Jeu adorable, vraiment cool pour ce détendre et addictif quand ont y prend goût.
Довольно спокойная игра для тех кто любит повозится на складе с коробками и любит тетрис. Она определенно стоит своих денег по скидке, кооп довольно приятный и разбавляющий атмосферу. Думаю на стим деке тоже можно поиграть т.к. игра не торопит и дает сколько угодно времени на подумать. За ошибки она можно сказать не наказывает, так что подойдет людям которые мало знакомы с играми или хотят чего-то милого и спокойного Из того что хотелось бы когда-нибудь увидеть в обновлениях: - Покупаемые апгрейды за денюжку что дают посетители почты - Возможность менять стеллажи в складах - Чуть быстрее темп открытия новых комнат - Больше типажей коробок, не хватает коробок в форматах 1х3 например или 6х2 чтоб меньше пустого места оставалось и была возможность играться в более разнообразный "тетрис" - Слова "в коробке" будут всегда значить картонную коробку (иногда это не картонных посылок)
quelle pépite de chill pas de chrono pas de pression juste une gestion tranquille et évolutive sans prise de tête merci aux devs :)
very fun and relaxing reconmend it fully
This has probably been written plenty of times in the reviews, but I can tell that a lot of love and care went into making this game. The artwork is beautiful, and the vibrant colours combined with the lighting give it a moody, magical atmosphere (not to mention the incredibly satisfying stamps). It’s safe to say that since I purchased this game, I haven’t been able to put it down! My absolute favourite part is the lack of timers, which is what makes it stand out from other simulation games that can stress you out with deadlines. This game lets you play entirely at your own pace. I’d highly suggest trying the demo—that is the route I took, and immediately after finishing it, I purchased the full game. Here is a quick breakdown of my experience so far: The Good: Satisfying Gameplay Loop: Fun and engaging mechanics based around taking orders from cats, sorting, stamping boxes with very cute stamp designs, and sending them off via a delivery cat on a ship. Zero Stress: The lack of timers is perfect. It allows you to sit back, take your time, and just enjoy the environment without rushing. Intriguing Progression: Unlocking new rooms by rummaging through piles is exciting, especially discovering new themed spaces. Flawless Presentation: The cosy lighting, vibrant colours, and cute cat animations are perfect. The music matches this moody, magical aesthetic flawlessly. The Bad: Save System: Lack of a manual save button to save your progress at any exact moment. At one time I had to exit the game to go and do other things and my last save was 9 min ago, so essentially I lost 10 min progress which is not major, but I'll still point it out. Verdict: If you want a cosy game with a beautiful environment to chill out in, I cannot recommend this enough. Thank you to the devs—I absolutely love the game you have created!
